The only species in the Pityriaseidae family, these birds live only on the island of Borneo. The tops of their heads are covered in yellow skin growths and the feathers of their lower throats and ear patches have a stiff, bristly texture. Traveling in flocks of six to ten, they hunt for invertebrates, such as caterpillars and beetles, along with some small reptiles and amphibians. They have been observed eating fruit, but this probably makes up only a small part of their diet. Little is known about their breeding habits, as they are fairly elusive birds. Classified as Near Threatened by the IUCN, they are at risk from deforestation and forest fires.
